T all whom t may concern i Y i Y Be it known that LfLEoYNARD W'. AsI-ILEY, a citizen of the United States,.res1ding at Milwaukee', in the county of Milwaukee and State of Wisconsin, have inventednew anduseful improvements in Trolley -AWheel Mounts, of which the following is a specication, reference being had tothe accompa-- ny'ing drawings, formingv a part thereof. f

AThe purpose of this invention isto provide an improved construction of trolleyl V Y wheel and harprfor electric railways.

Y construction shown and described, as indi#` v I5 p It consists inthe elements and features of cated in the claim.

In the drawings: `Figure 1 is a sectionl i. axial-with respect tothe wheeland with respect to the harp stein of a trolley wheel and harp embodying this invention. Fig. 2is an edge elevation of the saine, showing one side ing the wheel.` y In the structure shown inthe drawings,

theharp comprises atubularstein, l, by

which it is attached to a pole; a bridge or back" plate, 2;, a front* plate or retaining plate, 3, whi'chlis hinged to the stein, 1, for

' folding back from operativeposition, as.`

. shown in Fig. 2, and `a hollow trolleywheel bearing, 4, which is rigid with the back 6, adapted to be mounted for rotation upon the hollow bearing,v 4, and it is retained di thereon against'endwise displacementby the hinged front plate, 3, which has a circular aperture, 3a, to receive the protruding end of the wheel hub, Vand which shuts over the Y latter being interiorly threaded `for that `p urpose, and said plug or nut havingl inarendof the hub, as is shown inthe section .,view, Fig. 1. The front plate is retained in this position by means of anut or plug, 7,

which is screwed into the end of thehub, the

ginal flange, 7a, which extends over the Vfront plate. .This plug ornnut `is designed to be Y screwedfast into the endof the hub andV it place it is not in contact with any rotating part and it is Vtherefore not likely to become v funscrewed by accident.

will be observed that whenthus screwedinto The wheel ,hub is reduced ineXterior di- ,on the hub ends.

tures, 8a, in the contact springs being similarly tapered. Annular washers, 9,-9, are provided on the wheel hub outside the contact springs, said washers resting against the ends of the hub and thereby'` inclosing the Contact springs in' their respective seats The hub, at 6a, is interiorly grooved circumferentially; such grooving may be in the form of separate annular grooves Vor in the forni of a spiral groove, or thread, for thepurpose of hold- Ving lubricant between the Yinner surface of the hub and the outer Vsurface of the hollow bearing, t, and said hollow bearing has a plurality of apertures, 4a, to permit the passage out to the outerbearing surface of lubricant with which its axialcavity is designed to be stored. It will be observed that the nut or plug, 7, securely closes the interior cavity of the hollow bearing which thus serves as a secure `reservoir for lubricant,

and which may be initially so filled with lubricant that the plug or, nut, 7, in being screwed home, forces the lubricant out through the apertures, lla, lling the annular or spiral grooves in the inner surface of the hub, and so insuring perfect lubrication A from the first;V

Since onev purpose of the movable side plate is to affordA a positive support for the projecting end of the trolley wheel bearing, 4i, so as to guardv more securely against any bending orl springing of said it is desirable to have the end of the bearing Xed accurately in the aperand to this end it is necessary-that the side plate should be appliedj directly,-that iis, by direct axial Vniovernentonto theendjofthe bearing. And in order that it'inayl be thus applied and at A Y Y the saine time vmay be permanently connectameter at both ends for a .short distance,-`
